How to Choose Radiators

How to Choose Radiators
Radiator shopping tips
1. Buy radiators from a reliable company. (Lontek is a domestic radiator manufacturer with 10 years of experience, so the product quality and reliability is guaranteed).
2. You need to consider a number of factors before buying a radiator, like your residence's water quality, heating system (open or closed) and heating mode (individual heating or district heating). And you should pay attention to product use condition when buying a radiator.
3. Buy radiators and their accessories from the same company to avoid the accidents resulting from mismatch of the radiator and accessories during installation or use.
4. Since corrosion resistance of radiator is guaranteed by the company itself, so you should carefully check the corrosion resistance. Ask the seller to provide relevant test report, and do not buy the radiator whose certification doesn't include specific heat output.
5. Not install the radiator by yourself, leave the installation and maintenance work to professional person (like installer from the manufacturers)

Choose plate radiator or column radiator?
This is the question that is often perplexed us. Whether plate radiators or column radiators, they tend to transfer heat mainly by convection or radiation. Thermal radiation refers to heat transfer in space by way of electromagnetic wave, and its heating range is smaller (usually you can feel radiation within 1 meter). Convection refers to that cold and hot air circulates through exposed pipes to achieve heat dissipation purpose, and its heating range is larger. When using a plate radiator, a suction force will be caused due to its structure features, which can improve effect of forced convention, thus increasing the comfort of heating. But column radiator doesn't have this effect.
Plate radiator and column radiator can be chosen according to the actual needs. For room with a smaller space, like bathroom, you can select column radiator. Because this wall mounting type radiator can not only save room space but also can hang towel or small pieces of clothing through its horizontal column. For room with a large space, we advise you to buy a plate radiator. With added convection plate, this domestic radiator can achieve the best heat output (by way of radiation and convection) with the least time. Today, convector is the best choice for large rooms. In addition, convector can also be installed in places that were not suitable for radiators in the past, thereby effectively saving room space. At present, the anticorrosion problem of radiators has also been solved.
In addition to high-efficiency radiator, superior design and installation service are also available. In order to meet different style and color requirements, some radiator manufacturers provide custom heating solutions.
The failure of radiator's heat output will result in lower room temperature in the winter, which may influence your families' health. So when you choose a radiator, you should ensure the radiator you buy can maintain good heat dispersion performance under high temperature and strong pressure conditions.

Main quality problems
1. Heat output of the radiator doesn't meet standard requirement, which influences heating effect.
2. Below-grade accuracy of thread. The radiator must use threaded connection to form a circulating heating system. If the accuracy of thread doesn't meet requirement, the assembly of radiator will be influenced, bringing such problems as leakage.
3. Dimension tolerance and geometric tolerance are not up to grade, which will affect product assembly. The dimension tolerance of 600mm center distance radiator is ±2.0mm.
4. Thread center distance size surpasses the tolerance. Thread center distance index is very important for the quality control of die casting aluminium radiator. Below-grade thread center distance makes it difficult to assemble radiator fin.
